| 英文摘要 | the characteristic behavior of h-2 and o-2 over ceo2 and pt/ceo2 was studied by means of tpr,tpd,ftir and tpec. the reduction of ceo2 by h-2 is greatly pro moted by supported pt and highly labile adsorbed species is resulted. the tempera tures of sorption and liberation of h-2 on pt/ceo2 are lowered by as much as 300 degrees c than on ceo2. the oxygen adsorbed on partially reduced ceo2 exists as dioxygen species(o-2(-),o-2(2-)) at room temperature. on pt/ceo2 the oxygen species is altered and the dissociated species is formed even at ambient condition. the adsorbed oxygen on cerium oxide catalysts desorbs partly while the temperature is elevated and the retained oxygen is transformed into lattice oxygen ion above 170 degrees c. |
